Breaking Through the 80% Glass Ceiling: Raising the State of the Art in Word Sense Disambiguation by Incorporating Knowledge Graph Information

Neural architectures are the current state of the art in Word Sense Disambiguation (WSD). However, they make limited use of the vast amount of relational information encoded in Lexical Knowledge Bases (LKB). We present Enhanced WSD Integrating Synset Embeddings and Relations (EWISER), a neural supervised architecture that is able to tap into this wealth of knowledge by embedding information from the LKB graph within the neural architecture, and to exploit pretrained synset embeddings, enabling the network to predict synsets that are not in the training set. As a result, we set a new state of the art on almost all the evaluation settings considered, also breaking through, for the first time, the 80% ceiling on the concatenation of all the standard all-words English WSD evaluation benchmarks. On multilingual all-words WSD, we report state-of-the-art results by training on nothing but English

Generationary or “How We Went beyond Word Sense Inventories and Learned to Gloss”

Mainstream computational lexical semantics embraces the assumption that word senses can be represented as discrete items of a predefined inventory. In this paper we show this needs not be the case, and propose a unified model that is able to produce contextually appropriate definitions. In our model, Generationary, we employ a novel span-based encoding scheme which we use to fine-tune an English pre-trained Encoder-Decoder system to generate glosses. We show that, even though we drop the need of choosing from a predefined sense inventory, our model can be employed effectively: not only does Generationary outperform previous approaches in the generative task of Definition Modeling in many settings, but it also matches or surpasses the state of the art in discriminative tasks such as Word Sense Disambiguation and Word-inContext. Finally, we show that Generationary benefits from training on data from multiple inventories, with strong gains on various zeroshot benchmarks, including a novel dataset of definitions for free adjective-noun phrases.

Les marques de subjectivite dans le discours francophone de temoignage de Roberto Saviano

By turning truth into vision, the Italian writer Roberto Saviano, with the publication of Gomorra. Dans l’empire de la camorra in 2006 (2007 in French translation), a novel that tells the story of the power dynamics of camorra, has shaken up the international journalistic and literary panorama. The book lays the foundations for a new way of describing reality. The investigation becomes a literary discourse that relies on the word power and on the “I” of the author, an “I” that witnesses the search for an element of attraction that gives credibility to the story and ratifies a truth that would have otherwise been lost in the monotonous enunciation of the chronicle. In fact, in this case, the ethical result of the discourse is not achieved in the conformity between words and facts, but it becomes a guarantee that these words and facts will remain indelible in the memory. Gomorra outlines a documentary aesthetic which, using a new form of writing, transforms statistics, objective data and everyday life through a discourse that connects literature, anthropology, and sociology. The novelist’s subjectivity then becomes a witness and a symbol as well. In this sense, our study focuses on the analysis of subjectivity in the discourse Kerbrat-Orecchioni 2009), through the enunciator’s marks that create to the discourse of testimony. In addition, we will highlight the way how the author represents the complex reality of the camorra to the readers, which also earns him criticism during his reception in France

Quelques aspects sémantiques des verbes de déplacement transitifs directs: expérience didactique en classe de FLE

The teaching of notion of movement in foreign language classroom can be a particularly difficult didactic task, since object of the research is the study of an extralinguistic notion, such as physical movement. Our contribution is the result of a reflection born from our didactic experience in a university course of Franch linguistics where we reflected on the semantics of verbs in French, focusing on some direct transitive displacement verbs. What motivated the choice of this type of verbs is the identity of the situations they denote when they enter a specific construction, namely the direct transitive costruction where the roels of target and site are assigned to the subject and the direct object respectively. Indeed, even i these vebs describe a displacement, they do not all have a semantics that intrinsically implies a displacement. The study aims, in this regard, to expose our teaching experience in relation to reflection on what determines the semantic interpretation of expression as a displacement event in FLE learning

On Error-related Potentials during Sensorimotor-based Brain-Computer Interface: Explorations with a Pseudo-Online Brain-Controlled Speller

Objective: Brain-computer interface (BCI) spelling is a promising communication solution for people in paralysis. Currently, BCIs suffer from imperfect decoding accuracy which calls for methods to handle spelling mistakes. Detecting error-related potentials (ErrPs) has been early identified as a potential remedy. Nevertheless, few works have studied the elicitation of ErrPs during engagement with other BCI tasks, especially when BCI feedback is provided continuously. Here, we test the possibility of correcting errors during pseudo-online Motor Imagery (MI) BCI spelling through ErrPs, and investigate whether BCI feedback hinders their generation. Results: Ten subjects performed a series of MI spelling tasks with and without observing BCI feedback. The average pseudo-online ErrP detection accuracy was found to be significantly above the chance level in both conditions and did not significantly differ between the two (74% with, and 78% without feedback). Conclusions: Our results support the possibility to detect ErrPs during MI-BCI spelling and suggest the absence of any BCI feedback-related interference

A study of additional jet activity in top quark pair production and decay at the LHC

We report on the calculation of the NLO QCD corrections to top quark pair production in association with two hard jets at the LHC. We take into account higher-order effects in both the production and decays of the top-quark pair. The latter are treated in the narrow width approximation and $t\bar{t}$ spin correlations are preserved throughout the calculation. This is the first time that such a complete study for this process is conducted at NLO in QCD. We present results for fiducial cross sections at the integrated and differential level. Furthermore, we investigate kinematic properties of the additional light jets and their distribution in the $pp\to t\bar{t}jj$ process. We examine jets in production and top-quark decays as well as the mixed contribution, where the two hardest non-$b$ jets are present simultaneously in the production and decay processes.Comment: 6 pages, 2 figures, 2 table

A primary intraosseous squamous cell carcinoma case report and literature review. The new WHO classification

Abstract Aim: Cyst-like lesions in the mandible rarely develop into malignancies, and the re- ported incidence is between 0.3% and 2%. The present study describes a rare case of primary intraosseous squamous cell carcinoma of the mandible arising from an odon- togenic cyst. Materials and Methods: An 80-year-old male was referred to Trieste University Maggiore Hospital (Trieste, Italy), with acute pain in the left retromolar area. An initial examination revealed extra oral swelling without paresthesia of the IAN. Following an intraoral examination, the oral mucosa was edematous, percussion pain was experienced on the lower left second molar. Panoramic radiography revealed a re- tained lower left wisdom tooth and an irregular radiolucent area between the lower left second molar and the mandibular angle with clear margins. Computed tomography re- vealed diffuse bone resorption and an extensive loss of cortical bone on the lingual side. Results: A biopsy was performed during the surgery to remove the second lower left molar and the wisdom tooth, the pathological diagnosis was of squamous cell carcinoma arising from the epithelial lining of the odontogenic cyst. MRI with contrast agent was also performed. Shortly after the patient has been proposed a complete resective surgery of the mass including the infiltrated areas and then a reconstructive part to restore the function and aesthetic. Conclusion: The follow-up of a large inflammatory cyst is essential for early diagnosis of malignant neoplasm. This approach allows lower invasive treatments and major survival of these patients

3D Reconstruction, Digital Twinning, and Virtual Reality: Architectural Heritage Applications

Virtual Reality proposes different innovative solutions for the fruition of tangible, intangible, or no longer existing Cultural Heritage. The representation of architectural artifacts through virtual 3D models framed in immersive and interactive virtual environments allows building new paths of knowledge. This kind of narrative feeds the fruition, the understanding, and the involvement of the user. The article presents different examples of VR applied in the CH field, highlighting the VR capacities, foreshadowing possible future developments in the specific domain. The first case study describes the reconstructive digital modeling and the prototype application of VR aimed at rendering the interior space of the provisional hall of the First Italian Parliament, no longer existing, for the use of visitors to Palazzo Carignano in Turin. The second case study concerns the Charterhouse of Pisa in Calci and deals with two VR experiences realized for a new visit tour: 3D reconstruction of the illusory space depicted in a quadraturist frescoes and 3D representation of the layout of the cloister in its most important historical phases. The third case study deals with the reconstruction of the Cathedral of Carpi through a 3D interoperable BIM model and the new communication tool called “during time Digital Twin”, which uses a combination of VR and AR
